Ingersoll Rand has released three new sets of saw blades designed for its standard 1/2" shank air reciprocating saws. Engineered with bi-metal technology, the new blades increase the cutting surface area by 170 percent. The saw blades include fine, coarse and extra coarse tooth profiles with a new variable pitch blade that allows users to increase blade life while reducing blade vibration. “The new saw blades are the perfect complement to Ingersoll Rand air reciprocating saws,” said Michael Dugar, global product manager for Ingersoll Rand. “The bi-metal technology means faster, more precise cutting and longer blade life for our customers.” By applying high-speed steel to both edges of the backing material, the blades generate smaller chips, reducing frictional heat generated during the cutting application and enhancing overall blade performance. The new saw blades are available in quantities of six, 20 and 50 per pack and feature plastic cases for easy storage.
